How high should you fly over mountains?
Do not attempt a takeoff unless the loaded aircraft is below 10% the FAA certified gross weight, and the CG is within limits. Do not attempt a mountain flight unless the ceilings are at least 2000 feet above the highest terrain and visibility is at least 15 miles.
Does flying over mountains cause turbulence?
Rough air happens everywhere, from ground level to far above cruising altitude. But the most common turbulence experienced by flyers has three common causes: mountains, jet streams, and storms. Just as ocean waves break on a beach, air also forms waves as it encounters mountains.
What are the dangers of mountain flying?
High altitude flying can also cause pilots to experience a dangerous condition known as hypoxia. With increased altitude, atmospheric pressure decreases, and so does the amount of oxygen reaching the bloodstream. Hypoxia impacts functions of the brain and organs, causing impaired vision, muscle control, and judgment.
Can airplanes fly over mountains?
Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”

How does pressure affect the altitude of an altimeter?
Most of us understand that it uses pressure differentials to calculate altitude above sea level, and it is common place to receive barometric pressure settings to calibrate your altimeter based on the conditions of that area at that time. But is there anything else that might be impacting your altimeter? What about temperature?
What happens if your altimeter settings are incorrect?
Incorrect altimeter settings are a direct cause of altitude deviations, some of them severe enough to result in near mid-air collisions and controlled flight toward terrain. Fortunately, most of these deviations are detected following an alert from ATC, GPWS, or TCAS, and are corrected before the situations become truly perilous.
How does temperature affect the altitude of an airplane?
In conditions that are colder than standard temperature, the altimeter will overstate your altitude. The higher your altitude, the more it will be overstated. In conditions that are warmer than standard temperature, the altimeter will understate your altitude.
Why is my altitude lower than my altitude?
That’s the main reason why your true altitude is lower than your indicated. If you knew the actual static pressure in the valley, you could adapt your altitude by the rule of thumb: per 1hPa: 30ft
